One thing I do remember is that 100 is the smallest sample size you can have for a statistic to be "reliable", but the standard deviation is large.
Thus, I would not trust a study that is based off of just 100 samples.

Right, you would get an opposite result at a military school where most kids come from conservative families and 1 in 100 would be from a hippy group. If that kid happened to whine a little you would get the same result.
If a similar study was done in Grand Rapids, MI I am sure you could come up with a polarized result to Berkley CA.
